Executors

You can see a list of all the Executors in your cluster by clicking on the Executors menu item on the left panel. A new page is opened on the right, as shown below.

Executor Grid View

You can filter the Executors shown and you can also sort the table by clicking on the column headers. Clicking on an Executor name opens a new page for monitoring that Executor instance on the right, as shown below.

Monitoring Executors

On top of the page, there are two graphs that show various metrics of the Executor. See the graph section for more information.

Under these charts is the Executor Operation Statistics table. From left to right, this table lists the IP address and port of members, the counts of pending, started and completed executors per second, and the execution time and average start latency of executors on each member. Click on the column heading to ascend or descend the order of the listings.
